[PATCH v2 13/14] serial: msm: add SPL support for Qualcomm serial drivers

[Balaji Selvanathan]

Add SPL_MSM_SERIAL and SPL_MSM_GENI_SERIAL Kconfig symbols to
enable the Qualcomm UART DM and GENI UART drivers in SPL. Update
the Makefile to use the $(PHASE_) macro so both serial objects
build for both SPL and non-SPL phases.
